Power and Current for Estimating Supply Needs

When plugging devices into a PDU and UPS, do not exceed the current capacity

of the PDU nor the power output UPS. Tables 2-6 and 2-7 show the current

requirements of the common rack mounted devices.

Rack configuration utilities available from HP can help you plan the layout of

your rack. Full parts lists as well as diagrams of component positions and details

of power ratings are available. Refer to these if they are available. (See "Rack

Configuration Tools" in this chapter.)
